TOP GRILLE OR FAN MOTOR MOUNT ADJUSTMENT FOR FAN CLEARANCE
Sometimes during shipping, either the fan motor mounting or top grille may become out of alignment. This may cause the fan
motor blade to not clear the orifice ring. If this situation occurs, simply adjust either or both the fan motor mount or top grille
positions to allow proper clearance. The top grille four fastener insertion points to the plastic top and motor mount locations
are larger than the fasteners used to secure the grille and fan motor mounts. Use the procedures provided in figure 12 to
adjust for fan clearance.

THE FOUR MOUNTING POINT HOLES THAT SECURE THE TOP
GRILLE TO THE PLASTIC TOP ARE LARGER THAN THE
FASTENERS USED TO SECURE THE GRILLE. THIS IS ALSO TRUE
FOR THE FOUR FASTENERS SECURING THE FAN MOTOR TO THE
TOP GRILLE. TO PROVIDE MORE CLEARANCE, PREFORM EITHER
OR BOTH OF THE FOLLOWING PROCEDURES.
